Application of nitrosyl sulfuric acid

1. It is mainly used to substitute sodium nitrite in the diazo reaction of disperse dyes, so as to reduce the cost and improve the product quality;

2. Nitrosate, preparation of solid nitrogen salt, cyclic acid amine, etc.

Advantages of nitrosyl sulfuric acid

(1) It is easy to be used in the operation where there is no sodium bisulfate and the amount of sulfuric acid is relatively reduced;

(2) Reduce the consumption of sulfuric acid;

(3) No inorganic salt is produced;

(4) For diazotization, the content of nitrosyl sulfuric acid is greatly increased;

(5) The amount of "three wastes" has been greatly reduced

Typical Properties

It is mainly used to replace sodium nitrite in diazo reaction of disperse dyes, so as to reduce cost and improve product quality.
